HOOP-SHAVING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 429,376, dated June 3, 1890.

Application filed lioven ber 14, 1389. $erial No. 330,333. (No model.)

To ail whom it may concern:

Be it known that 1, WILLIAM P. CURTISS,f

State of Ohio, have invented a new and Inn proved Hoop-Shaving Machine, of which the following is a full, clear, and exact descrip-' i of the shaft b.

tion.

My invention relates to that class of machines adapted to the making and shaving of wooden hoops, and the object of my invention is to provide a rapid and efficient, machine for shaving and heveling all kinds of wooden hoops.

To this end my invention consists in certain features of construction and combination of parts hereinafter described, and more specifically pointed out in the claims.

Reference is to he had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan or top view of the ma chine, parts being broken out; Fig. 2, a side elevation of the same; Fig. 3, a front elevation of the machine; Fig. 4, an enlarged plan of the front portion of the machine, showing the tops of the legs and post with knives attached and the toggle-joint for operating the inner leg or post; and Fig. 5, an inside detail View of the two parts of the carriage and the link by which they are attached.

The machine is provided with a long rect angular frame A, in which is journaled the shaft a, to which power is applied to run the machine through the pulley B. The pulley B is loosely mounted on the shaft a, and is provided with a clutch-section 0.. adapted to be engaged by a clutch-section b on a sleeve 0', splined to the shaft and operated by a lever d, whereby the machine can be started or stopped as required. The shaft a is connected by suitable gearing to the shaft 1), which operates the working parts of the machine.

One side bar of the frame A is provided with a carriage made in two parts (J and D, which are connected together upon the inside of the frame by the link (I, one end of which is provided with a slot, for a purpose hereinafter described.

The carriage O D is provided with tongs e,

which are attached at the pivot of their jaws to the part D and by their arms to the part C through the toggle-joint f, the pivot of which is attached to a bar g of the carriage C. The end of the bar g is provided with a pin g, which connects it with the pitman E, which is connected by the pin 72. to the crank To the inside of the leg H of the frame A is pivoted the lower end of the post J, which is connected at its upper end with one end of a toggle j oint 7c, the other end of which is pivoted at 3 to the free end of a spring 4, attached to the frame. This end of the toggle projects beyond the pivot 23, and is pivoted in a slot 5 of a slideZ on the frame A, which slide is connected by a pin m with a pitman n, which is in turn connected with a crank 0 on the shaft 19.

To the top of the leg H and post J are attached the shaving-knives n p. The leg and post are also provided with guide-springs q q to guide the hoop 'r. The post J is also provided with a strip 3, which extends over the springs q q and prevents the hoop r from getting out of place. To the front of the leg H is attached a slide t, carrving a plate a, which moves vertically in the slide, and to which are attached the knives v v for beveling and cutting off the hoop. These knives come together at the bottom and separate toward the top, so that as the plate u, to which they are attached. is raised, they will grad ually bevel the hoop, and finally cut it off. The plate u is connected by a rod to to one end of the bell-crank 50, which turns on the pin 1, the other end of said crank being attached to the rod 3 which passes through a clip 2 on the carriage C, where it is retained by a pin 6, passed through one of a series of holes in the end of the rod.

The machine is operated as follows: The end of a hoop ris inserted between the knives when they are in an open position. As the shaft 1) revolves it operates on the crank =21 and pitman E and starts the carriage C and D. The slot in the link at will allow the part 0 to start first, thus straightening the toggle f and closing the jaws of the tongs e firmly upon the hoop r. A spring2 on the fraineA, bearing on the part D of the carriage, assists in retaining the part D while the, part 0 is started. The continued backward motion of IOO the carriage draws the hoop it i entire length between the knives p 19, t i: shaving it throughout. When the hoop is nearly shaved, the clip 2 on the carriage (J strikes the pin 6 in one of the holes of the rod g, thus'tipping the bell-crank m and raising the rod 10, plate a, and knives 1; 0, and tapering and cutting of the hoop 7". It will be readily seen that the length of the hoop and the point at which it is beveled may be regulated by the pin and holes in the end of the rod 3 While the above operation is going on, the revolution of the shaft 1) also acts on the crank o and pitman n, drawing back the slide Z, which, acting on the toggle k, bends it and draws the post J away from the leg I-I, thus opening the knives p p. The machine is then ready for another hoop. The spring 4, attached at one end to the frame A and carrying one end of the toggle 70, provides a certain amount of elasticity as theknives p 19 close upon a hoop.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hoop-shaving machine, the combination, with a pivoted knife-carrying post, of a toggle-lever pivoted at one end to the post, a spring attached to the frame to which the lever is pivoted, a slotted slide engaging the lever, and means for moving the slide, substantially as shown and described.

2. In a hoop-shaving machine, the carriage O D, having the two parts thereof connected by the link d, and having the tongs eand toggle f mounted thereon, in combination with pin g, pitman E, pin h, crank 'i, and shaft b, for operating said carriage and tongs, substantially as described.

3. A hoop-shaving machine having a movable post pivoted to afront leg of the machine, said post and said leg being provided with knives p p, and having toggle it, slide Z, pitman 'n, and crank 0 for actuating said post, thus opening and closing the knives, substantially as described.

4. The combination of the knives p p and springs q q with the leg H and post J, said post having toggle k, slide 1, pitman n, and crank o for actuating the same, substantially as described.

5. In a hoop-shaving machine, the plate u, adapted to move in the slide 1, and having the knives 1* attached thereto, in combination with rod 10, bell-crank :0, rod 1 and clip .2 for imparting motion to said plate, substantially as described.

6. A hoop-shaving machine consisting, essentially, of a two-part carriage sliding on the side of the frame and carrying tongs adapted to grasp a hoop and drag it through the machine, and having asuitable pitman and crank for actuating said tongs and carriage, a movable post pivoted to afrontleg of the machine, said post and leg being provided with suitable shaving-knives and guide-springs, and having means, substantially as described, for actuating said post, thus opening and closing the shaving-knives, and vertically-movable knives aflixed to a plate on the front of the machine,'adapted to bevel and cut off the hoop, and having means, as shown, for actuating said knives, all arranged and combined substantially as in the one shown and described.
